In 2009, Knighton was cast as Bryce Varley in the science fiction series FlashForward, based on the novel by Robert J. Sawyer. Knighton had originally auditioned for the role of Demetri Noh but lost out to John Cho. The show's co-creator David S. Goyer then rewrote the role of Bryce Varley for Knighton.[4] The show was axed after one season.
